如果该场的强度和相位以数值数据形式给出，则无参考相位全息术会生成完整的（幅度和相位）光场。它基于两个纯相场的干涉，这两个纯相场是由两个相互相干的平面波在硅型液晶的两个相位调制空间光调制器处反射而产生的。因此，可以显示任何真实或人造 3D 场景的任何光场。这意味着无参考相位全息术是未来 3D 成像（例如三维成像）的一种有前途的方法。 g。在 3D 电视中。本文介绍了该方法的原理，并提出了三种可能的干涉仪布置，其中首次采用了适用于该应用的马赫-曾德干涉仪和光栅干涉仪。解决了计算给定 3D 场景的衍射场的可能性和问题，给出了算法的最佳选择和修改。给出了几个新颖的实验示例来证明 3D 线索景深、遮挡和视差。指出了相对于其他全息方法的好处和优势，讨论了尚未解决的问题和必要的技术发展以及可能性和未来前景。图形摘要
Referenceless phase holography generates the full (amplitude and phase) optical field if intensity and phase of this field are given as numerical data. It is based on the interference of two pure phase fields which are produced by reflection of two mutually coherent plane waves at two phase modulating spatial light modulators of the liquid crystal on silicon type. Thus any optical field of any real or artificial 3D scene can be displayed. This means that referenceless phase holography is a promising method for future 3D imaging, e. g. in 3D television. The paper introduces the theory of the method and presents three possible interferometer arrangements, for the first time the Mach–Zehnder and the grating interferometer adapted to this application. The possibilities and problems in calculating the diffraction fields of given 3D scenes are worked out, the best choice and modifications of the algorithms are given. Several novelty experimental examples are given proving the 3D cues depth of field, occlusion and parallax. The benefits and advantages over other holographic approaches are pointed out, open problems and necessary technological developments as well as possibilities and future prospects are discussed.Graphical Abstract
